BACKGROUND AND PURPOSE Few studies have investigated the relationships between asymptomatic carotid lesions and silent infarcts confirmed on magnetic resonance imaging. METHODS A consecutive series of 117 subjects (average age, 62 +/- 9.4 years) who were free from neurological deficit but had at least one established risk factor for stroke were investigated by B-mode carotid ultrasonography a...

BACKGROUND A non-invasive estimation of cerebral perfusion pressure (CPP) using transcranial Doppler sonography was assessed in brain-injured patients by comparing conventional measurements of CPP (difference between mean arterial pressure and intracranial pressure) (CPPm) with the difference between AP(mean) and the critical closing pressure of the cerebral circulation (CPPe). METHODS Twenty...

Vasospasm following traumatic brain injury (TBI) may dramatically affect the neurological and functional recovery of a vulnerable patient population. While the reported incidence of traumatic vasospasm ranges from 19%-68%, the true incidence remains unknown due to variability in protocols for its detection. Only 3.9%-16.6% of patients exhibit clinical deficits. Compared to vasospasm resulting f...

STUDY OBJECTIVE Nearly all emergency medicine residency programs provide some training in emergency physician-performed ultrasonography, but the extent of emergency physician-performed ultrasonography in community emergency departments (EDs) is not known. We seek to determine the state of ultrasonography in community EDs in terms of access to ultrasonography by other specialists and performance...

Brain death is clinically diagnosed by verification of the absence of brain stem reflexes, motor responses, and the ventilatory drive.1 In some circumstances, ancillary tests are necessary to confirm the diagnosis of brain death, especially when there is uncertainty about the reliability of parts of the neurologic examination or when an apnea test cannot be performed. Ancillary tests are also u...

BACKGROUND AND OBJECTIVE The aim of the study was to determine the correlation of hypoxic-ischemic (HI) brain injury in full-term neonates detected via ultrasonography (USG) and blood flow parameters evaluated via Doppler sonography (DS) with long-term outcomes of mental and neuromotor development at the age of 1-year. MATERIALS AND METHODS In total, 125 full-term neonates (78 subjects of cas...

CONTEXT Endoscopic ultrasonography is considered a highly accurate procedure for diagnosing small pancreatic tumors and assessing their locoregional extension. OBJECTIVE To evaluate the impact of endoscopic ultrasonography on the management of pancreatic adenocarcinoma in clinical practice. PATIENTS Sixty-four consecutive patients (mean age 70.5 plus/minus 11.9 years) hospitalized for stagi...

Objective: The aim of this study was to use ultrasonography for the diagnosis and confirmation of Pulled Elbow treatment.Methods: This descriptive cross-sectional study initiated in 2014 and continued until 2015. We used simple sampling method and recruited 60 samples among patients aged 4 months to 6 years. The apparatus used in this study was an ultraso...

Since impaired gallbladder emptying contributes to gallstone formation, the evaluation of gallbladder motility requires accurate methodology. Recently developed 3-dimensional ultrasonography may take into account various gallbladder shapes more accurately than conventional 2-dimensional ultrasonography. Therefore, volumes of water-filled balloons of various sizes were determined in vitro by 2-d...

Objective- This study was conducted to make a full understanding of the anatomic and ultrasonographic characteristics of digestive canal in Persian Sturgeon and provide standard approaches for performing digestive tract ultrasonography on this sturgeon species.Design - Experimental studyAnimals - 30 mature Persian sturgeons (Asipenc...
